CMS doesn't have to run all the time. You can turn it on and off trivially.

There are start-menu entries to start and stop the CMS service if it really is a concern.

I have been toying with DS4 a little and for the first time ever I am able to make some sense of how to do things. So they finally improved it IMO.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
